Eyes ALE, PME subequal, larger than PLE, ALE oval, PME circular, PLE oval; posterior eye row procurved from front; ALE separated by less than their radius, ALE-PLE touching, PME touching for less than half their length, PLE-PME separated by less than PME radius. Sternum longer than wide, yellow-brown, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV; setae abundant, densest laterally (fig. 54E). Mouthparts: chelicerae, endites, and labium pale orange; cheliceral setae dark, evenly scattered. Labium anterior margin indented at middle; with six or more setae on anterior margin.
